1 READ AND FOLLOW SAFETY INSTRUCTIONS!This is the safety alert symbol. When you see this symbol on your pump or in this manual, be alert to the potential for personal about hazards that will cause serious personal injury, death or major property damage if about hazards that can cause serious personal injury, death or major property damage if about hazards that will or can cause minor personal injury or property damage if label NOTICE indicates special instructions which are important but not related to hazards.

Abrasive materials in the water cause component wear and reduce pump capacity and discharge pressure. Never use the pump to develop or clean the well. Permanent pump damage can result within the first few hours of the well casing is suspected of being crooked, check it with a gauge of identical length and diameter as the pump and motor with two lengths of pipe attached. Serious dam-age can result if the pump becomes lodged in a crooked sure the well can supply a high-capacity Turbine pump.

3 The well should be deep enough to cover the pump unit with water, even at extreme pumping rates. Typically, the pump should be submerged 10 to 20 feet below the lowest water level and at least 5 feet above the bottom of the entrained in the water reduces performance and will dam age the pump is designed to provide maximum efficiency under specific capacity and head conditions. Do not oper-ate it beyond specified controls and pump must match. Do not inter-change controls with other models. Serious damage can result to the unit if pump and controls do not control systems and pump units are repairable in the field. To avoid serious damage to the unit, use only parts obtained from authorized number of starts per day will influence motor and control component life (starters, relays, capacitors, etc).

Make a strong mechanical bond between the motor leads and the cable to avoid high resistance at the connection. A poor mechanical con nection, or a poorly wrapped splice, can cause motor problems and motor connecting the motor to the cable, perform a ground check to assure that the motor has not been damaged. Attach one end of an ohmmeter lead to any of the three motor leads and the other ohmmeter lead to the pump intake bracket.

5 A new motor must have a resistance of 2 megohms or greater. If not, contact your dealer. Repeat for all three the cable and make the mechanical connections (Figure 1A) and splices as follows:1. Cut motor leads and corresponding cable ends at 3-inch spacings to stagger connections for a smooth Cut connecting cable to match the motor leads. NOTICE: Match color coded wires, red to red, black to black, and white to When using a butt connector, expose bare wire for about 1/2 . When using stranded wire, expose about 1 of wire. NOTICE: Butt connectors may be used with solid wires through 8 AWG, or stranded wires through 10 Clean exposed ends of wire thoroughly with emery cloth or sandpaper to assure good electrical BUTT CONNECTORS (Figure 1A): Insert wires into con nector until insulation butts up against connector.

Clean each strand and push strands of cable into matching (color-coded) open strands of the motor Wrap entire length of joint with fine copper wire until strands are Apply heat and solder. Solder will follow the heat; make sure solder flows throughout the joint. Pull firmly on cable to test Repeat Step 5 for each Taping splice (Figure 1B): Because friction tape is not water resistant, never use friction tape on a water-tight splice. Use Scotch Number 33, or Clean joints and adjoining cable/wire insulation of all grease and dirt, and build up joint area with tape until it matches diameter of Starting 1-1/2 back from the joint, firmly apply one layer of tape, overlapping about half the previous lap and continuing approximately 1-1/2 beyond joint.

10 Cut tape evenly and press both ends firmly against Apply two additional layers of tape, as described in Step 7B, beginning and ending 1-1/2 beyond the previous starting/ending and Cable Continuity TestBefore installing pump check cable and splices as follows (see Figure 1C):1. Submerge cable and splice in steel barrel filled with water. Make sure both ends of cable are out of Clip one ohmmeter lead to barrel. Test each lead in cable successively by connecting the other ohmmeter lead to the three cable leads, one after the If resistance reading goes to zero on any cable lead, a leak to ground is present. Pull splice out of water. If meter reading changes to infinity (no reading) the leak is in the If leak is not in splice, slowly pull cable out of water until reading changes to infinity.
